Spinal Nerves: Plexus I01:22

Spinal Nerves: Plexus I

3.1K
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...

Sympathetic Pathways: Sympathetic Chain Ganglia01:20

Sympathetic Pathways: Sympathetic Chain Ganglia

6.7K
The sympathetic chain ganglia, also known as the sympathetic trunk ganglia or paravertebral ganglia, are a series of ganglia located bilaterally on either side of the spinal column. These ganglia serve as relay stations for the sympathetic nervous system. Preganglionic neurons originating in the spinal cord project their axons to the sympathetic chain ganglia. Within the ganglia, these preganglionic fibers synapse with postganglionic neurons.The postganglionic neurons of the sympathetic trunk...

Peripheral Nervous System: Ganglia and Nerves01:24

Peripheral Nervous System: Ganglia and Nerves

6.4K
The Peripheral Nervous System (PNS) is a crucial component of the body's neural network, extending beyond the central nervous system (CNS) to bridge the gap between the CNS and the external environment. It encompasses nerves, ganglia, and sensory receptors.
Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...

Cranial Part of Parasympathetic Division01:18

Cranial Part of Parasympathetic Division

2.4K
The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.
The vagus nerve (cranial nerve X) alone accounts for approximately 75...

Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla01:27

Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla

3.1K
The sympathetic pathways of the collateral ganglia and adrenal medulla serve unique but interconnected roles in the sympathetic response.
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...

Detailed Structure and Function of Lymph Nodes01:23

Detailed Structure and Function of Lymph Nodes

5.4K
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Area of Science:

  • Orthopedics
  • Radiology
  • Neurology

Background:

  • Joint capsule tears can lead to extraneural (paralabral) and rare intraneural ganglion cysts.
  • Intraneural ganglion cysts are fluid-filled sacs developing within a nerve.
  • The articular theory suggests these cysts arise from intra-articular joints.

Observation:

  • This report presents two novel cases of axillary intraneural ganglion cysts.
  • Cases were incidentally discovered during magnetic resonance imaging (MRI) studies.
  • Coexisting lesions included lymphadenopathy and suprascapular nerve entrapment.

Findings:

  • The first documented instances of axillary intraneural ganglion cysts visualized with MRI.
  • Demonstrates the presence of intraneural ganglion cysts in the axillary nerve.
  • Highlights the association of these cysts with other pathologies.

Implications:

  • Reinforces the validity of the articular theory for intraneural ganglion cyst formation.
  • Expands the known anatomical locations for intraneural ganglion cysts.
  • Suggests MRI is valuable for diagnosing these rare nerve-related cysts.
